Versuchsvorschrift

A solution of benzoyl chloride (32.5 g, Aldrich) in ether (200 ml) was added dropwise to a stirred solution of m-cresol (25.0 g, Aldrich) and triethylamine (27.2 g, Aldrich) in ether (500 ml). The reaction mixture was stirred at room temperature for 1 hour then filtered. The ethereal filtrate was washed with saturated NaHCO3 and water then dried over Na2SO4. The ether layer was separated, dried and concentrated in vacuo to give the desired product (104.0 g) as a white solid, mp 45-47C. 1H NMR consistent with the desired structure.
